AT&T announces upgrades to 3G air-interface and backhaul connections

AT&T issued a press release announcing an upgrade of its wireless network air-interface to High-Speed Packet Access (HSPA) 7.2 Mbps technology.

Of equal note is the company’s comments on its backhaul connections. Not only can older backhaul networks constrain data throughput, they can fail to meet latency requirements for good-quality VoIP. AT&T says most of its mobile backhaul data will be carried on fiber-based, HSPA 7.2-capable backhaul networks by the end 2010, with deployment continuing into 2011.
